The macros which extract registers from a struct sigcontext are no
longer needed and can be removed. They are starting not to build
anyway, given the removal of the 'e' and 'r' from register names
during the x86 merge.

That's not enough, unfortunately. If we go that way, we need to add
dependencies on !UML for several options.

Some register accessor cleanups -
userspace() was calling restore_registers and save_registers for no
reason, since userspace() is on the libc side of the house, and these
add no value over calling ptrace directly
init_thread_registers and get_safe_registers were the same thing,

This patch removes a variable which was not used in two functions.
Yet another code cleanup, nothing really significant.
Please note that I could not test this on x86_64. I don't have the
hardware for it.

uml: fix an IPV6 libc vs kernel symbol clash
On some systems, with IPV6 configured, there is a clash between the kernel's
in6addr_any and the one in libc.
asm/page.h is disappearing from the libc headers and we don't need it anyway.

Instead of writing entire structures between UML and the I/O thread,
we send pointers. This cuts down on the amount of data being copied
and possibly allows more requests to be pending between the two.
This requires that the requests be kmalloced and freed instead of
living on the stack.

This patch starts the removal of a very old, very broken piece of
code. This stems from the problem of passing a userspace buffer into
read() or write() on the host. If that buffer had not yet been faulted
in, read and write will return -EFAULT.
To avoid this problem, the solution was to fault t
HOST_FRAME_SIZE isn't used any more. It has been replaced with MAX_REG_NR.

If there's a segfault inside the kernel, we want a dump of the registers
at the point of the segfault, not the registers at the point of
calling panic or the last userspace registers.

a number of the small functions are either unused, in which

Not intrusive, much more trivial than Bodo's patch, to merge for 2.6.13.
